Sometimes you want to show 3 data sets in one chart with very different data ranges, for example:
  • 1,000s of customers
  • $ sticker price per unit
  • Number of products bought per customer
One solution:
  • Set the column of the first data point of each series to 100
  • Calculate the 2nd value relative to the 100
  • Manually paste data labels with the correct factors
The chart below gives an example:
  1. The first chart contains the unadjusted data
  2. The second chart shows the adjusted version
  3. The third charts shows the values I have entered in the PPT columns
